For example user want to upgrade their Apollo essential 16.6 to Apollo adv/pro 16.6 while keeping all existing services in their Apollo essential database (PostgreSQL).
Is this possible?
The answer is Yes.
Customer just need to install Apollo adv/pro using existing database, and Apollo adv/pro pickup existing PostgreSQL database without deleting previous Apollo essential's services.
Here are the detail workflow tested by Apollo development team: 1. Install Apollo Core 2020 2. Configure Postgres(10) database 3. Add additional services and datatsets. 4. Uninstall Apollo Core but selected to remain the configuration file 5. Run Apollo Pro/Adv 2020 installer suite. 6. Install Apollo 7. Configure Apollo (use default settings but point to the existing Postgres database used by previous Apollo essential)
